Never experienced any colorpicker problems on my Windows GIMP ... ever. Can you be more specific?

While using the colorpicker, hold Shift to display the pixel info
dialog. The left column should list "Red/Green/Blue" values. If it
only lists "Value", this is because you're not actually selecting from
the layer:

1 - If you're currently editing a layer mask, then the colorpicker will only return a grayscale "Value", because layer masks are a grayscale channel.
2 - Same goes for if you have QuickMask active, because then it's picking from the selection channel.

Sorry to be not very clear. I'm referring to the eyedropper in the "Foreground change color" and the issue is present also if I click the eyedropper in the one-only layer picture. Try it.

You mean holding down Ctrl with a paint tool to activate colorpicker mode? Tried that and worked perfectly - unable to reproduce the described behavior.

In a single layer image with no transparency, always picked the pixel's color value.

In a multi-layer image with or without transparency, always picked the pixel value from the active layer only, it had no effect (retained previous picked color) outside the active layer area. Found no apparent way to make the colorpick modifier (as opposed to the colorpicker tool) sample from all layers.

Another very important note: Transparent pixels within a layer still retain their original color value. If, for example, you paint a HSV spectrum onto a layer and then erase it to transparency, the colorpicker will still pick the color pixels from it. Which brings to mind that the default "color" for a transparent area is black.

I suspect that Francesco had the same problem I did. In the color picker
dialog box, there is an icon, about 2/3 of the way from the top, which
when one hovers the mouse cursor over the icon, reveals the context help
that one can select a color from anywhere in the screen. When one's
cursor is located over a GIMP window, this is true, one can select a
color; when the cursor is over a part of the screen that is not part of
a GIMP window, the cursor reverts from the eyedropper shape to the
normal cursor shape, and in my experience, one was not able to select a
color from any part of the screen that was not a GIMP related window.

This is a known gtk+ issue in windows (bug 653653) at bugzilla.gnome.org.

Apart from checking, whether 2.8.2 still has it, and then telling us?
Well, praying on knees seems to be popular :)

I downlod newest Gimp today. And I used to change the fg color in color dialog. Today I foud out that color picker tool exist. So it works(hope). But it is the right that eyedropper doesn´t work. Like in "color to alpha" dialog in 2.6 version.

Select Color picker tool and in Tool Options dockable dialogue toggle
Set_foreground_color instead of Pick_only. Now when you use eyedropper from
Change_Foreground_Color dialog window it will change foreground color to the
one you picked. This will help you restore your workflow til the bug is
fixed.Francois wrote

GIMP 2.8 per Windows, problem with the color picker

Hello friends, it's 2014 and i just updated gimp to 2.8.10 from 2.8.2 and am still getting issue with ALL COLOR PICKERS linked from any of the dialogs. The color picker always returns black color regarless of where you click. I am on RDP, Win7 x64 Slovak. This really makes Gimp useless.

The very basic GUI color picker works well when somewhat inconveniently
switching from my present tool to the color picker tool. Hotkeys sort of
solve this.

Thankfully, holding down 'Control' (in Windows/Linux) results in the color
picker temporarily popping up before reverting to present tool upon release
of the key.

But one of the absolute best ways to pick color has been clicking on the
present colors to get the color dialogue, so you can work with the pallet
and get any visible on-screen color, which is one of the most amazing and
useful tools built into 2.6 that *is lost* in 2.8, according to some. Like
DSunhammer, I have the same bug — where (I guess) someone simply forgot to
change the present selection to the color detected. It just makes the
present selection pure black #000000. So close to being useful!

Otherwise, pretty great work on the new version in all other aspects, and I
look forward to the next version where hopefully our great in-dialog color
picker returns! (Any chance for a patch?)
